Definitions

  • the invention relates to transparent softening agents comprising special ester quats and auxiliaries, such as fatty acid amidoamines and quaternization products thereof, betaines, nonionic surfactants, polyols and/or derivatives thereof, alcohols and/or hydrotropic agents.
  • special ester quats and auxiliaries such as fatty acid amidoamines and quaternization products thereof, betaines, nonionic surfactants, polyols and/or derivatives thereof, alcohols and/or hydrotropic agents.
  • ester quats is generally understood as meaning quaternized fatty acid triethanolamine ester salts, which are widely suitable for softening both fibers and also hair.
  • conventional quaternary ammonium compounds such as, for example, the known distearyldimethyl-ammonium chloride, to a large extent out of the market as the result of a better ecotoxicological compatibility.
  • Overviews on this theme are given, for example, by O. Ponsati in C. R. CED-Congress, Barcelona, 1992, p. 167, R. Puchta et al. in Tens. Surf. Det., 30, 186 (1993), M. Brock in Tens. Surf. Det. 30, 394 (1993) and R. Lagerman et al. in J. Am. Oil. Chem. Soc., 71, 97 (1994).
  • ester quats of the prior art have very good performance properties and satisfactory biodegradability and good skin cosmetic compatibility
  • the preparations containing ester quats known from the prior art are cloudy.
  • the object of the invention was to provide preparations containing ester quats which, even after storage, did not turn cloudy and at the same time have good softening and antistatic behavior. Furthermore, such preparations should facilitate the ironing of textiles.
  • the invention provides transparent softening agents comprising
  • Alkanolamines which are suitable for the purposes of the invention as central nitrogen compounds may contain an alkane radical having 1 to 4 carbon atoms. Preference is given to using triethanolamine and products of the addition thereof and 1 to 10 and preferably 2 to 5 mol of ethylene oxide. Also suitable are mixtures of triethanolamines, such as, for example, methyldiethanolamine with triethanolamine and the like.
  • Fatty acids are to be understood as meaning aliphatic carboxylic acids of the formula (I) R 1 CO—OH (I) in which R 1 CO is an aliphatic, linear or branched acyl radical having 6 to 22 carbon atoms and 0 and/or 1, 2 or 3 double bonds.
  • Typical examples are caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, elaostearic acid, arachidic acid, gadoleic acid, behenic acid and erucic acid, and technical-grade mixtures thereof which are produced, for example, during the pressurized cleavage of natural fats and oils, during the reduction of aldehydes from the Roelen oxo synthesis or the dimerization of unsaturated fatty acids.
  • Preference is given to technical-grade fatty acids having 12 to 18 carbon atoms, such as, for example, coconut, palm, palm kernel or tallow fatty acid, preferably in hydrogenated or partially hydrogenated form
  • Dicarboxylic acids which are suitable as feed materials for the purposes of the invention conform to the formula (II), HOOC—[X]—COOH (II) in which X is an optionally hydroxy-substituted alkylene group having 1 to 10 carbon atoms.
  • Typical examples are succinic acid, maleic acid, glutaric acid, 1,12-dodecanedioic acid and, in particular, adipic acid.
  • the fatty acids and the dicarboxylic acids can be used in the molar ratio from 1:10 to 10:1. However, it has proven advantageous to set a molar ratio of from 1:1 to 4:1 and in particular 1.5:1 to 3:1.
  • the trialkanolamines on the one hand and the acids, i.e. fatty acids and dicarboxylic acids taken together, can be used in the molar ratio 1:1.2 to 1:2.4.
  • a trialkanolamine:acids molar ratio of from 1:1.5 to 1:1.8 has proven optimal.
  • the esterification can be carried out in a manner known per se, as is described, for example, in international patent application WO 91/01295.
  • the esterification is advantageously carried out at temperatures of from 120 to 220° C. and in particular 130 to 170° C. and pressures of from 0.01 to 1 bar.
  • Suitable catalysts which have proven successful are hypophosphorous acids and alkali metal salts thereof, preferably sodium hypophosphite, which can be used in amounts of from 0.01 to 0.1% by weight and preferably 0.05 to 0.07% by weight, based on the feed substances.
  • alkali metal and/or alkaline earth metal borohydrides such as, for example, potassium, magnesium and, in particular, sodium borohydride
  • the cocatalysts are usually used in amounts of from 50 to 1000 and, in particular, 100 to 500 ppm, again based on the feed materials.
  • Corresponding processes are also the subject-matter of the two German patent specifications DE 4308792 C1 and DE 4409322 C1, to the teaching of which reference is expressly made here. It is possible to use mixtures of the fatty acids and dicarboxylic acids, or else to carry out the esterification with the two components one after the other.
  • ethoxylated trialkanolamines can be used. This has the advantage that the alkyleneoxy distribution in the subsequently resulting ester quat with regard to the three OH groups of the amine is approximately equal.
  • a disadvantage is that the esterification becomes more difficult for steric reasons.
  • the method of choice therefore consists in alkoxylating the ester prior to quaternization. This can be carried out in a manner known per se, i.e. in the presence of basic catalysts and at elevated temperatures.
  • Suitable catalysts are, for example, alkali metal and alkaline earth metal hydroxides and alkoxides, preferably sodium hydroxide and, in particular sodium methoxide; the feed amount is usually 0.5 to 5% by weight and preferably 1 to 3% by weight, based on the feed materials. If these catalysts are used, free hydroxyl groups are primarily alkoxylated. If, however, the catalysts used are calcined hydrotalcites or hydrotalcites hydrophobicized with fatty acids, insertion of the alkylene oxides into the ester bonds also occurs. This method is preferred if an alkylene oxide distribution is desired which is close to that when alkoxylated trialkanolamines are used.
  • the alkylene oxides used may be ethylene oxide and propylene oxide, and mixtures thereof (random or block distribution).
  • the reaction is usually carried out at temperatures in the range from 100 to 180° C.
  • the incorporation of, on average, 1 to 10 mol of alkylene oxide per mole of ester increases the hydrophilicity of the ester quats, improves the solubility and decreases the reactivity toward anionic surfactants.
  • the quaternization of the fatty acid/dicarboxylic acid trialkanolamine ester can be carried out in a manner known per se.
  • the reaction with the alkylating agents can also be carried out in the absence of solvents, the co-use of at least small amounts of water or lower alcohols, preferably isopropyl alcohol, is recommended for the preparation of concentrates which have a solids content of at least 80% by weight and in particular at least 90% by weight.
  • Suitable alkylating agents are alkyl halides, such as, for example, methyl chloride, dialkyl sulfates, such as, for example, dimethyl sulfate or diethyl sulfate, or dialkyl carbonates, such as, for example, dimethyl carbonate or diethyl carbonate.
  • the esters and the alkylating agents are usually used in the molar ratio 1:0.95 to 1:1.05, i.e. in virtually stoichiometric amounts.
  • the reaction temperature is usually 40 to 80° C. and in particular 50 to 60° C. After the reaction, it is advisable to destroy unreacted alkylating agent by adding, for example, ammonia, an (alkanol)amine, an amino acid or an oligopeptide, as is described, for example, in German patent application DE 4026184 A1.
  • the agents according to the invention can comprise the ester quats in amounts of from 5 to 70% by weight, preferably 15 to 60% by weight and in particular 30 to 40% by weight, based on the final concentration.
  • Suitable stabilizers are fatty acid amidoamines and/or quaternization products thereof, betaines, nonionic surfactants and/or polyols.
  • Fatty acid amidoamines which are suitable as component (b1) represent condensation products of fatty acids with optionally ethoxylated di- or oligoamines, which preferably conform to the formula (III),
  • R 5 CO is a linear or branched, saturated or unsaturated acyl radical having 6 to 22 carbon atoms
  • R 2 is hydrogen or an optionally hydroxy-substituted alkyl radical having 1 to 4 carbon atoms
  • R 3 and R 4 independently of one another, are hydrogen, a (CH 2 CH 2 O) m H group or an optionally hydroxy-substituted alkyl radical having 1 to 4 carbon atoms
  • A is a linear or branched alkylene group having 1 to 6 carbon atoms
  • n is a number from 1 to 4
  • m is a number from 1 to 30.
  • Typical examples are condensation products of caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, elaostearic acid, arachidic acid, gadoleic acid, behenic acid and erucic acid, and technical-grade mixtures thereof with ethylenediamine, propylenediamine, diethylenetriamine, dipropylenetriamine, triethylenetetramine, tripropylenetetramine, and adducts thereof with 1 to 30, preferably 5 to 15 and in particular 8 to 12, mol of ethylene oxide.
  • ethoxylated fatty acid amidoamines here is preferred because the hydrophilicity of the emulsifiers can in this way be adjusted exactly to the active ingredients to be emulsified.
  • fatty acid amidoamines it is also possible to use the quaternization products thereof, which are obtained by reacting the amidoamines with suitable alkylating agents, such as, for example, methyl chloride or, in particular, dimethyl sulfate, in accordance with processes known per se.
